[py3] Use "utf-8" as input encoding for docutils in rest extension Docutils says that "unicode" is an unknown encoding on Python3. Not sure where "unicode" as an encoding comes (it's there since showtime) but "utf-8" seems more appropriate. From now on, rendering of CubicWeb's rst directive (e.g. ..winclude) works on Python 3. Accordingly, we extend wdoc's test to demonstrate this. For this we need to install docutils in tox's web environment.

[py3] Avoid setting attribute on Element instance in wdoc view This change is needed to make "wdoc" view work on Python 3. Indeed, before this patch, we used to set a "parent" attribute on Element instances, which is not permitted since Python 3.3 as xml.etree.ElementTree uses the C implementation by default. To get rid of this "parent" attribute, we rework the XML nodes processing logic to return and retrieve a node along with its parent in several place of the code. Namely, build_toc_index() now accepts the "parent" value for "node" and inserts it in the "index" dict (thus avoid `node.parent = <value>`). Respectively, every query to the "index" dict is updated to also retrieve the "parent" (thus avoiding `<value> = node.parent`). Later in InlineHelpView class, the "index" dict is bound to "tocindex" attribute so we adjust how it is queried in respective methods. Tests cubicweb/web/test/unittest_views_wdoc.py now pass on Python 3.

[test] Add a trivial test for "wdoc" view We just make sure it gets rendered without errors (which wasn't the case before the previous patch). It does not work on Python 3; this will be fixed in next changeset.

[py3] Open rst file in text mode in wdoc view Otherwise, UStringIO complains that it receives bytes.

[ext/rest] Drop "handle_io_errors" argument to docutils' FileInput This argument is deprecated and ignore in docutils since version 0.10. Besides, its default value is None which is the same as we passed.

[wdoc] Remove fallback about xml.etree module Module xml.etree exists since python 2.5.

[wdoc] Avoid usage of deprecated xlm elementree getchildren() method Use list(node) as suggested by the deprecation warning.

[style] Make cubicweb/web/views/wdoc.py flake8-clean

[py3] Use six.text_type instead of unicode in wdoc views

[views/startup] drop a duplicate rql query in manage view Counting entities in `nb` is already done above this code, regression introduced by a85db6fa

Added tag 3.26.4, debian/3.26.4-1 for changeset e1c1af68db86

[pkg] Version 3.26.4

[py3] ensure AjaxController return bytes publish() must return bytes, when the @ajaxfunc decorated method return None, this raised: TypeError: You cannot set Response.body to a text object (use Response.text)

[py3] Let InstanceCommand.run_arg() always return an int The caller of this method (which is method "run_args") does `max(status, self.run_arg(appid))` and run_arg might return None if the underlying <cmdname>_instance method returns None. On python3 max(1, None) breaks with "TypeError: unorderable types: int() > NoneType()". So we enforce run_arg() method to return an integer even if the underlying method returns None. This fixes call of "cubicweb-ctl i18ninstance" with Python3.

[test] Use cubicweb-file < 2.0.0 From version 2.0.0, cubicweb-file moved to new-style layout (Python package) but we still expect it to be an old-style cube in CubicWeb's tests (WebconfigTC in web/test/unittest_webconfig.py).

[py3] Decode subprocess stdout in toolsutils.show_diffs() On Python 3, subprocess' pipes are bytes stream so we must decode them before printing. Without this change, diff of configuration files (e.g. all-in-one.conf as displayed upon instance upgrade) will rendered as a single line on Python 3.

[python3] make sure staticcontroller returns a bytes instance The ``publish()`` method of controller is supposed to return a bytes intsance. Returning a text_type instance will crash later on in the Pyramid response handler when assigning content to ``response.body`` (at least in Python3):: >>> from pyramid.response import Response >>> r = Response() >>> r.body = '' Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/adim/.virtualenvs/…/response.py", line 562, in _body__set raise TypeError(msg) TypeError: You cannot set Response.body to a text object (use Response.text)

[python3] use inspect.getfullargspec instead of inspect.getargspec The latter is now deprecated

Depend on cubicweb-file >= 2.0.0 I applied V1 of the patch, but V2 contained this extra hunk...

[test] Update webconfig's tests accounting for cubicweb-file being now a package WebconfigTC.test_locate_all_files and WebconfigTC.test_locate_resource assumed that cubicweb-file was installed in <share>/cubes/file whereas, from the latest release, it is now a standard Python package thus installed in site-packages as cubicweb_file. We simply update base directory of these two tests.

[utils] Fixes compatiblity of QueryCache with expected dict interface QueryCache is expected to mimick the interface of the dict built-in. The current __iter__ implementation breaks this expectation by iterating over key, value pairs instead of only the keys. This changeset fixes this issue by changing the __iter__ implementation to iterate over the keys in the cache and providing an implementation of the items method with a contract identical to the dict build-in (return a copy of the key- value pairs within the dictionary as a list).

[test/statsd] add tests for cubicweb.statsd_logger
